Quality check the IFC
Firstly, check the model that the objects have been classified using an IFC viewer.
Everything in the class Object will become Generic Models. In this model, everything except rooms and openings have been classified correctly. Quickly check the model beforehand, so as not to start a new project with a questionable underlying model.
Should look like this:
Start Project
When linking an IFC model, there are a few things to think about before.
It’s possible to “link” an IFC in two ways, either “Link IFC” or “Open IFC” and save a Revit model. Always use Link IFC.
When linking an IFC Revit will automatically convert it into a Revit file which it links into the project. Revit will use the top Revit project template in the list. This can result in several levels which don’t make sense.
It’s recommended to change the order of the templates in Revit options, so a Naviate Bimfire template is on top.
- Go to File on the top left. If the file tab is not visible, change to home first.
In the bottom right, go to Option. - Go to File Location, and use the arrows to move up the template to the top position.
-
To link a model, open either a floor plan or a 3D view.
It will always link via Origin to Origin. Make sure that the IFC is exported with the local coordinate system.
-
The levels from ArchiCAD will appear in Revit.
- Use Copy/Monitor to receive the levels into the specialist model.
- In Option bar, select Multiple
- Select all levels and finish in Option bar.
- Create a set of floor plans,
- Views For Sheets
- Unconnected
- Modified&Deleted
- Work Views
- The project browser will now be populated with different views.
- Go to view for sheet views. The default appearance is underwhelming, to say the least. Because from the start the IFC doesn’t show us the necessary information such as room information, no opening swings, etc
- To get the appropriate floor plan information, use the floor plan DWG's.
- Use these settings for each DWG on each floor plan.
- Select the DWGs and change Draw Layer to Foreground.
-
This should make the floor plan look presentable for drawings.
- Finish by hiding the entire IFC link in Visibility/Graphics override. Go to the View template in the floor plan.
- Turn off the IFC in Revit Link tab
- Select the DWG and use the Query button to select a layer on an object, to turn off that layer.
- Hide the layer in view.
- Go to work views and use Wall & Door requirements on the walls and openings in the view. They will appear in the Views for sheet views. Make sure to enable IFC Mode first.
Deliver data from the specialist model.
Export the data
The model will result in something like this:
- In the Revit template from Bimfire there exist already schedules which can be used for export to excel.
- Export a schedule from the model.
Excel
From ArchiCAD, it's necessary to export one schedule/excel from each category. There will be one Excel for i.e. Wall, Doors, and Windows.
Open the Excel file that is sent from the Architect, which is a schedule from ArchiCAD with agreed-upon parameters.
The pictures below will be in Swedish, but the text will refer to English formulas and tabs.
May vary by region.
- Go to the tab, Data, link data from text/CSV file.
- Read the data.
- Once the data is in excel, use this formula
=XLOOKUP(lookup_value;lookup_arry;return_array;return_array;[if_not_found])
=XLOOKUP(C3;'IFC Door Rating Export (3)'!B:B;'IFC Door Rating Export'!C:C;"-")
XLOOKUP checks for the Value in Row C3, and sees if it exists in column B, in sheet IFC Door Rating Export.
If it exists, write the value from column C in sheet IFC Door Rating Export, but. if it does not exist write the value "-"
-
End with copy the entire column, and use Paste -> Values Only
